Claims.

This invention relates to improvements in Wa-.

ter sampling devices and it consists of the matters hereinafter described and more particularly pointed out in the appended claims.

It is common practice to take samples of 1000- motive boiler water so that it may be analyzed to determine the various constituents thereof and the proper treatment to be administered thereto to make it more suitable for use. Heretofore, the usual custom was to take a piece of rubber tubing and place it upon a short stub pipe which is associated with a valve on the water glass and gage cock of the locomotive. The other end of the hose Was placed in the mouth of a container, such as a glass bottle of convenient size, andthe valve opened so that boiler water flowed into the container. There are several objections to this practice. First, the stub pipe referred to is located usually in a very confined and awkward position, making it diflioult to attach therubber tubing. Second, the boiler water is very hot and there is considerable steam discharged with the water. Due to the position of the parts mentioned and the necessity of the operator to hold the hose in one hand and the container in the other hand, there is danger of hot water and steam scalding the operator taking the sample.

One of the objetts of the present invention is to provide a simple, inexpensive and efficient device by which a water sample may be taken from a locomotive boiler with safety to the operator avoiding the danger of being scalded by hot water or steam.

Another object of the invention is to provide a device of this kind which may be conveniently held in one hand of the operator, thus leaving the other hand free for such duties as may be required at this time.

Again, it is an object of the invention to provide" a device of this kind from which steam may readily escape before the steam and hot water enter the container, thus eliminating breaking of the container due to an accumulation of pressure therein.

Also, it is an object of the invention toprovide a water sampling deviceof this kind which contains no valves, springs or other parts requiring adjustments and service so that the device is capable of continued use over a long period of time.

The above mentioned objects of the invention, as well as others together with the several advantages thereof will more fully appear as the specification proceeds.

In th drawing:

Fig. 1 is a vertical sectional view through a water sampling device embodying the preferred form of the invention.

Fig. 2 is a horizontal sectional view through the device as taken on the line 22 of Fig. 1.

Referring now in detail to that embodiment of the invention illustrated in the drawing, the improved device embodies therein an upright hollow body 5 preferably made of metal. It includes an upright cylindrical side wall 6, a domed top wall I and a bottom end tubular neck 8. Said neck, which is of smaller diameter than the body, is internally threaded to receive the complementary and externally threaded neck 9 of a receiver III, which may take the form of an ordinary glass bottle. In the bottom of the body is a perforated plate ll, against which a rubber gasket l2, in the upper end of the neck engages. In turn said gasket is adapted to be engaged by the lip end of the neck 9 to provide a good tight connection between the body 5 and the container l0.

Opening through one side of the domed top wall 1 of the body is a nipple l3 having parts l3a and I3?) disposed outside and inside of the body respectively, the axis of said nipple being inclined to the perpendicular axis of the body. A tubular open ended sleeve M, of relatively fine mesh screen, is fixed at its upper end to the part I3b of the nipple and the lower open end of said sleeve is disposed to discharge substantially axially of the body 5 and neck 8. a

A rubber tube l5 has a friction fit at its bottom end on the nipple part l3a and an angle nipple I6 is frictionally' fitted in the upper end of said tube. While the tube 15 is flexible, it is still stiff enough to stand in its normal upwardly inclined condition without such bending as will cause the.

tube to kink or collapse; Thus while the axis of the upper end of the nipple I6 is disposed parallel with the axis of the body 5, it is spaced laterally from said axis and is located at a point considerably above the domed top. of the body.

A plurality of holes ll is formed in the upper portion of the side Wall 5 of the body adjacent the nipple I 3 and through which steam may escape from the interior of the body to atmosphere. On the opposite side of the body and midway between its top and bottom ends is an upright radial flange or rib l8 disposed in a slit or kerf in the inner end of a handle I9. Screws 20 pass, through said inner end of the handle and said flange or rib to secure the handle to the body. Preferably the handle is made of poor heat conducting material. so that it remains cool enough at all times to be comfortably held in the hand.

When drawing a sample of water from a locomotive boiler, the device asa whole, with the container l0 connected thereto, is held in one hand by means of the handle l9. While thus held, the nipple I6 is caused to engage with the stub pipe associated with the gage glass valve of a locomotive boiler. Using the other hand, said valve is opened and steam and Water under boiler pressure flow into the nipple l6 and down the tube I and through thenipple l3 and sleeve I4 and into the body '5. While the the sleeve is made of screen that presents a large number of openings, these are relatively small or fine and the water, being more or less solid, will be guided in the general directionof the length of the sleeve to be discharged into the bottom of the body to 7 pass through the openings in the plate II and into the receiver bottle III. In the passage of the water and steam down the sleeve M, a part of the steam will pass through the openingstherein to enter the top end of. the body and there mingle with the steam that may arise from the bottom of the body; This steam will then escape through the openings H in the body to atmosphere. As

the handle I9 is on that side of the device opposite the openings I1, it is apparent that the steam escaping therefrom cannot engage the hand grasping the handle. Thus, fromthe foregoing it is apparent that the entire device including the container or bottle III is held by one hand and this in a manner so that the hand cannot be scalded. 1

-It is also apparent thatas water enters the reis closed and the device withdrawn from the stub pipe. The container or bottle I0 is then unscrewed from the neck and a cap is applied to the bottle so that it may be transmitted to the laboratory for test purposes.

It is to be noted that the device comprises but a, few parts which are not relatively movable and that there is a complete absence of small parts and springs so that the device cannot readily get out of order.

While in describing the invention I'have referred in detail to the form and arrangement of the parts, the same is to be considered only in the illustrative sense so that I do not wish to be limited thereby exccept as may be specifically set forth in the appended claims.
